The screw terminals accept the motor leads and the control loop; the contactor mount means it clips onto the S0 contactor without extra DIN-rail space. Verify the contactor coil voltage matches the control circuit before wiring.","metaTitle":"Siemens 3RB1025-1PB0 Electronic Overload Relay, 1.5...6 A, C","metaDescription":"Siemens 3RB1025-1PB0 electronic overload relay, 1.5...6 A, for contactor mount, class 10, screw connection, manual reset, size S0.
